Today, I casually mentioned to my mom that my boyfriend of two years and I were thinking about moving in together. She looked me dead in the eye and said if I ever moved out, she'd throw me out of the house. I'm confused. FML

Oh wow! It actually got posted! I'm the OP here, and I'm 19, the reason I'm confused is because when I finished high school he and I were going to move down to Florida together so I could go to college, and I got really sick, so we stayed here. My mom was completely fine with it when we were going to move out of state but now that we're moving to the apartment complex not even a mile away.
I asked her for clarification and she told me that I knew what she meant. So I asked my dad, and he told me the same thing.
I think they might be screwing with me.

Maybe she meant if you announce that you are actually going to move, like in two weeks when the apartment is ready, she is going to throw out all of your stuff and kick you out before your actual move date screwing you over a little?
